DS200RTBAG2AFB is a relay terminal board (RTBA) designed for General Electric’s Mark V board series. This board can be used in applications across a number of GE brand drives and exciters. By installing this board into a drive cabinet an additional ten relays are provided to the user. Both the LAN I/O terminal and a remote user can drive the relays found on this board.
Locations K20 through K29 are the board positions for all onboard relays. DS200RTBAG2AFB includes two types of relays, DPDT and 4PDT. DPDT type comprises seven of the relays found on the card, including K20 through K26. These types feature two Form C contacts, with each contact rating 10A. K27 through K29 are the second relay type, 4PDT. Rather than two, 4PDT relays include four Form C contacts that each rate 1A. All ten of these points are protected by a 130 VAC metal oxide varistor (MOV). Each relay contains an internal 110 VDC coil that ensures they are operating properly. Should any relay stop functioning or break, the user can easily remove and replace all ten spots.
Provided parameters regarding installation and storage guidelines for DS200RTBAG2AFB should be followed. This will ensure the integrity of the board and the overall drive system. Both the device’s manual and datasheet give a detailed installation and wiring guide for this board. Members of the Mark V board series were originally provided technical support by the manufacturer, General Electric.
